Abstract: The features of the multimode steady-state generation of superradiant heterolasers, in which quantum dots with a long incoherent relaxation time serve as an active medium, while low-$Q$ combined Fabry–Perot cavities with a distributed feedback of counter-propagating waves serve as cavities, are studied. It is shown that due to the quantum-coherent dynamics of optical dipole oscillations and population inversion of the working levels in a quantum-dot ensemble with strong inhomogeneous broadening of the spectral line, the simultaneous lasing of modes with various degrees of phasing and/or correlation and with qualitatively different dynamic behavior, notably, quasi-stationary, metastable, self-modulation, pulse-periodic, and quasi-chaotic is possible.

Keywords: superradiant laser, low-Q combined cavity.
